AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION INNOVATION PATENT CLOUD BASED VERSATILE SYSTEM FOR RADIOLOGICAL IMAGES The following statement is a full description of this invention, including the best method of performing it known to me FIELD OF THE DISCLOSURE The present disclosure relates to the field of radiology imaging and medical data 5 sharing. More particularly, the present invention relates to accessing, compressing/ de compressing, annotating, and sharing radiological images, opinions and diagnostic comments over a cloud. 0 DEFINITIONS OF TERMS USED IN THE SPECIFICATION The expression 'user' used hereinafter in the specification refers to but is not limited to a radiologist, a medical doctor and a medical staff. 5 The expression 'terminal' used hereinafter in the specification refers to but is not limited to mobile phones, laptops, tablets, desktops, iPads, PDAs, notebooks, net books and the like, including wired or wireless computing devices. 0 The expression 'radiological data' used hereinafter in the specification refers to but is not limited to images, radiological information, discussion, study / reference material in any form including audio / video information. 25 The expression 'facility' used hereinafter in the specification refers to but is not limited to hospital, clinic and laboratory. The above definitions are in addition to those expressed in the art. 30 BACKGROUND Radiology is one the most significant aspects in medical industry that has great usage and applicability in medical diagnosis. Users are capable of interpreting 5 images such as those obtained by conventional radiology, Ultra-Sonography (US), Computed Tomography (CT), angiography systems and Magnetic Resonance Imaging (MRI). As these imaging techniques have rapidly evolved technically, more anatomical details are available for non-invasive assessment. For practicing users, it is relatively difficult to be aware of all possible imaging 0 presentations of various diseases. An issue that confronts users is that they require empirical medical information for effective diagnosis. To accomplish the above stated diversified objectives, users refer to reference books or conduct web searches or utilize terminals to access and study past medical cases which is a time consuming factor. While accessing relevant information, delays may 5 occur due to system failure, server breakdown, system being unable to handle large multimedia files, application compatibility issues, which in turn reduce the user's efficiency of diagnosis. Prior art solutions and platforms enable users to use their terminals for obtaining 20 or viewing or interpreting radiological data. Some of the available prior art solutions and platforms even have a dedicated Picture Archiving and Communication System (PACS) server for DICOM images and other type of medical images, but most of them lack one or other functionalities. One of them being non flexibility i.e., they are designed to work only with a particular 25 vintage or type of PACS system. Secondly they are not ready for integration with cloud services. Typically, the information required by a user to arrive at appropriate diagnosis is usually available in books, web forums, blogs, or via interaction with other users. However, accessing such data may result in delays 2 during relevant information retrieval process in the limited time frame available for effective diagnosis of the patients' reports. A user typically deals with various issues with regards to obtaining and 5 interpreting information from the images. Firstly, the information is not presented in an optimal manner. In clinical practice, a user is confronted with specific morphological patterns of diseases at specific locations in the radiological images. The radiological images are often low resolution images due to the fact that they are compressed and sent over a communication 0 network. To improve clarity of the low resolution radiological images, a user needs to download the image file and manually edit the file to improve resolution of the image. Also, annotation of areas of interest in the image files is one of the demanding tasks that assist in accurate and effective analysis in radiological cases. 5 Secondly, most prior art solutions use terminal dependent Operating Systems (OS). This restricts versatile implementation of solutions in a terminal. For example, if mobile solutions are based on the android platform; one may effortlessly execute the application in any android based terminal without much 20 hassle. But the same mobile solutions cannot be executed on Apple iPad which is based on Mac OS. This necessitates development of different solutions compatible with every OS available in the market. Accordingly, a customer needs to purchase the same application software more than once for different platforms/ terminals. 25 Again, the prior art solutions and platforms do not facilitate sharing of radiological images along with annotated areas of interest and discussion threads with desired user. Therefore, there is felt a need for a system that assits 3 users to access, view, annotate, comment upon and share patients' radiological data with desired users. OBJECTS 5 Some of the objects of the present disclosure aimed to ameliorate one or more problems of the prior art or to at least provide a useful alternative are described herein below: 0 An object of the present disclosure is to provide a cloud based versatile system for annotating, exchanging and rendering radiological images.

The examples used herein are intended merely to facilitate an 7 understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein. 5 Radiological image annotating, exchanging and rendering systems known in the art are plagued by issues including lack of on-demand and effective retrieval of radiological data, systems are memory intensive and localized, lack of compatibility with different operating systems and the like. The system and 0 method as envisaged in the present disclosure aims to overcome these issues in prior art. The system and method of the present disclosure assists users in annotating, exchanging and rendering radiological data for effective and efficient medical 5 diagnosis. The cloud based radiological image annotating, exchanging and rendering versatile system of the present disclosure is Operating System (OS) independent and can be executed on any terminal. To accomplish the above stated feature, 20 the terminal must comply with basic requirements including but not restricted to internet access and high resolution display capabilities. In accordance with another embodiment of the system of the present disclosure, the terminal executing the system is independent of the type of Picture Archiving and communication system (PACS) integrated within the cloud. The cloud based 25 system of the present disclosure facilitates handling of large image files, typically of sizes in excess of 100MB, which is an effective and an agile alternative to Picture Archiving and Communication System (PACS) integrated in non cloud based radiological image annotating, exchanging and rendering system. The system envisaged by the present disclosure facilitates automatic 8 generation of reports, graphs, summary and preparation of corresponding study material for future references. The present disclosure envisages a cloud based radiological image annotating, 5 exchanging and rendering system with a flexible and generic architecture. In accordance with one aspect, the system envisaged by the present disclosure is integrated into a cloud. In accordance with another aspect, the system envisaged by the present disclosure is integrated with any Picture Archiving and Communication System (PACS). 0 The system and method of the present disclosure will be described herein below with reference to FIGURES 1 to 5. FIGURES 1(a) and 1(b) illustrate a flow diagram of a cloud based versatile 5 system for radiological image annotating, exchanging and rendering in accordance with the present disclosure. A user who is typically a radiologist, a medical doctor or a medical staff operates the system envisaged by the present disclosure on his/her terminal. A 20 majority footprint of the system of the present disclosure resides on a terminal with some part on a backend server typically hosted by the facility utilizing the system of the present disclosure. The system prompts the user to enter his/her login details displayed on the terminal. The system includes an acquiring module configured to elicit login credentials from users. The acquiring module, 25 after acquiring the user's login credentials, verifies the login details with those stored in a backend repository. Once the user's login credentials are verified by the back end repository, the system displays a dashboard area on the display screen of the terminal. If the user's login credentials do not match with any data stored in the backend repository or is not found (in case of a new user), a 9 message is displayed on the user's terminal indicating that there is no match for the user's login details, and the user is prompted to re-enter his/her login credentials. New users of the system need to register themselves to access relevant radiological information using the system. Once a new user has 5 registered himself/ herself with the system, the system assigns privileged access rights to the newly registered user. The mapping of the access rights to the new users is accomplished by a secure mechanism which is hierarchical in nature and resides in the system. The backend repository stores radiological data along with the login credentials of registered users. The radiological data is typically 0 stored in compressed P - list format. FIGURE 2 illustrates a user dashboard of the system of FIGURE 1(a) and 1(b) that entails a plurality of functionality modules. 5 Typically, subsequent to registration, a user is able to view his/her dashboard 200 which entails a plurality of functionality modules that enables the user to perform desired tasks. As shown in FIGURE 2 of the accompanying drawings, the various features include a directory 210, guide 212, opinions/discussion 214, setting 216, profile 218 and reports 220. The user generates a request for 20 radiological data which is either informational data or multimedia data. The multimedia data include images, video or audio clips of the user's interest. The information accessed by the user is pre-loaded or loaded upon specific request by the linked facility's Picture Archiving and Communication System (PACS) on to the private or public cloud via a secure mechanism. User access rights to 25 the cloud are controlled in a hierarchical manner. FIGURE 3 illustrates various functionality tools 300 incorporated within the system to enable implementation of the features shown in FIGURE 2. The functionality tools 300 include annotation tool 310, contents transfer tool 312, 10 multimedia editing tool 314 and display control tool 316. The annotation tool 310 enables the user to annotate areas of interest in a freehand manner on the radiological data. The contents transfer tool 312 enables the user to share the contents with other experts in the field or to upload data back onto the cloud. 5 The multimedia editing tool 314 enables the user to edit audio / video content of radiological data and to write comments on a discussion thread around radiological data. The multimedia editing tool 314 enables the user to write comments on desired topics by means of a virtual / physical keyboard associated with the terminal. The comment provided by the user is securely 0 shared with other users who are associated with the same discussion topic. Another functionality of the multimedia editing tool 314 is to store metadata along with the associated compressed image in a P-list format thus forming a professional authenticated and encrypted sharing network for medical professionals. 5 The display control tool 316 enables adjusting of the luminance, chromaticity and scaling (including resizing and zooming) of the multimedia contents. The image scaling function enables a user to manipulate clarity of a selected radiological image. Furthermore, the user is enabled to zoom-in/ zoom-out the 20 selected image to provide annotation on a desired location on the terminal 14. The cloud based radiological image annotating, exchanging and rendering system of the present disclosure provides fast compression of multimedia files for uploading and fetching data securely on to the terminal. In an embodiment 25 of the present disclosure, the system has the ability to de-compress radiological images on the fly. The downloaded radiological images are displayed on the display screen of the terminal. This enables fast exchange of encrypted data from the cloud. 11 Referring to FIGURE 4, there is shown a flowchart illustrating the key steps included in the method for implementing the cloud based radiological image annotating, exchanging and rendering system of the present disclosure. The method, in accordance with the present disclosure includes the following key 5 steps: - embedding a customized solution on a terminal accessible to a user; - executing the customized solutions on the terminal; - prompting the user of the terminal to enter corresponding login credentials; 0 - acquiring the corresponding user login credentials through the terminal; - transmitting acquired login credentials to a backend server for the purpose of verification; - displaying a dashboard containing a plurality of functions, on the terminal; and 5 - enabling the user to annotate the fetched radiological images at desired location, using freehand. - Commenting on the images and share them.
